INTRODUCTION - 8 - CLEANING_Cleaning System Components

Question Title

* 1. Enter first and last name

Question Title

* 2. As milking machines become more complex, the task of assuring adequate circulation and mechanical cleaning action in all parts of the milking machine becomes increasingly difficult.

True

False

Question Title

* 3. Select all that apply. The following are components of the cleaning system that are connected to the milking machine in different locations:

Wash controller

Wash vats (or wash sink)

Manifolds and delivery lines

Air injector

Water injector

The claw

Question Title

* 4. Select all the options that match the cleaning component with its corresponding duty.

Wash controller: Fills the wash sink with water and mixes cleaning chemicals

Wash controller: Admits air to move cleaning solutions around the milk lines

Air injector: Admits air to move cleaning solutions around the milk lines

Wash manifold: Transports cleaning solutions from the wash sinks to the milking units and milk lines

Question Title

* 5. The wash valve ensures a one-way path for wash solutions around the milk-line.

True

False

Question Title

* 6. The air injector may be located on a wash water delivery line or on the milk-line.

True

False

Question Title

* 7. The milking units are commonly attached to ___________ which are fed solution from the wash manifold.

Jetters

Wash valves

Air injectors

Wash vats

Question Title

* 8. The clean-in-place (CIP) process includes transporting cleaningsolutions from the wash sink through the sanitary parts of the system and backto the wash sink.

True

False

Question Title

* 9. The milk pump's capacity is important because:

It must be large enough to return all the cleaning solution to the wash sink

It must be small enough to maintain a high velocity

The milk pump's capacity is not an important factor in the cleaning system

Question Title

* 10. The distribution of water flow between units _______.

Should be varied in pulses to provide the highest cleaning benefits and avoid exceeding the capacity of the milk pump.

Does not matter.

Should be as uniform as possible to make the most efficient use of water and avoid exceeding the capacity of the milk pump.

Question Title

* 11. Why is drainage an important aspect of cleaning?

Standing water in the system increases the risk of bacterial growth between milkings and mixing of different cleaning chemicals.

Standing water counts as a loss of water and it is important to make the most efficient use of water to avoid exceeding the capacity of the pump.

Standing water leads to the dilution of the milk during the next milking.

Question Title

* 12. In most situations, the vacuum pump capacity recommended for milking is less than that required for the cleaning of milking machines.

True

False

Question Title

* 13. Select all that apply. Operating procedures for cleaning should include instructions on:

Operation of any manually controlled valves, pipes and switches

Chemical handling (including checks for empty chemical containers)

Washing of external surfaces of the milking machine, milking parlor and milk room

Question Title

* 14. With all of the advanced cleaning techniques and systems hand cleaning is no longer important.

True

False
